Nerf gun mistaken for gun, school locked down

Cupertino High School was locked down Monday morning after a janitor reported seeing a gun in a student's backpack, Santa Clara County sheriff's spokesman Sgt. Jose Cardoza said.

The sheriff's office received a report at 8:25 a.m. of a male, possibly a student, with a gun in his backpack. The custodian, according to Cardoza, saw a black handle sticking out of the backpack and immediately called the sheriff's office.

Deputies responded and set up a perimeter around the school.

Meanwhile, another call came in about 12 minutes later that the confirmed student had been contacted to find a NERF gun in his backpack, Cardoza said.

School staff told deputies 20 to 30 other students also brought NERF guns to school to play a game, Cardoza said.

No students were arrested but some met with the principal about the possible school violation.
